Another day, another OTA update for a Samsung tablet. Today it’s the Galaxy Tab S 8.4 on AT&T, which is receiving a bump to Lollipop (hurrah!). The update is to 5.0.2, not a more stable version like 5.1.1, but be grateful that you’re at least getting all the goodness that comes with Lollipop.
This information is courtesy of a support page on AT&T’s website, which also says that the size of the update is over 1.1GB, so you’re going to need at least that much space available to download and install it.
As per usual, updates delivered by the major carriers tend to have notoriously slow roll-outs – waiting a week or more to see it come down on your device is totally normal. To check if it’s been pulled down to your device, open the Settings app, find “About device,” then tap “System updates.”
